Subject:	Header problems building cross gcc i686-pc-linux-gnu to i686-pc-cygwin
Reply-To:	cygwin AT cygwin DOT com

Hello all,

I am having problems building a GNU/Linux to Cygwin cross compiler.
I configure gcc using:

../../foreign/gcc-2.95.3-4/configure --target=i686-pc-cygwin
--with-target-headers=/win32/c/Cygwin/usr/include/
--prefix=/home/jcast/ --with-as=/home/jcast/bin/i686-pc-cygwin-as

When I attempt to build (using `make'), I get the following error
message:

for name in _muldi3 _divdi3 _moddi3 _udivdi3 _umoddi3 _negdi2 _lshrdi3 \
_ashldi3 _ashrdi3 _ffsdi2 _udiv_w_sdiv _udivmoddi4 _cmpdi2 _ucmpdi2 \

Any help would be greatly appreciated; I do not want to have to build
Cygwin apps from within WinDOS (I just want to support other people's
brain-damaged choices, not have to make those choices myself).
